ABSTRACT

Disclosed herein are system, apparatus, article of manufacture, method, and/or computer program product embodiments for a mobile device based control device locator. An embodiment operates by receiving a request to locate a control device, transmitting acoustic token transmission information to the control device to activate an electroacoustic transducer on the control device, receiving an acoustic signal including an acoustic token signal from the control device via a plurality of acoustic sensors, and determining distance information of the control device based on the received acoustic token signal generated by the electroacoustic transducer of the control device.

BACKGROUND

Field

This disclosure is generally directed to locating a control device using a mobile device. More particularly, this disclosure relates to mobile device based control device locators.

Background

Consumer electronics such as, for example, high definition audio and/or video play back devices, typically provide a remote control to enable a user to operate, select, and/or playback available audio and/or video content on a display connected to the high definition audio and/or video playback device. However, due to the inconspicuous nature of remote controls, consumers or users of a high definition audio and/or video play back device will often not remember or misplace where they may have physically placed the remote control after several hours of non-use. This problem may be further exacerbated when several users share the use of the high definition audio and/or video play back device and each user may not physically place the remote control in a prominent location for each other to use. Consequently, it may be difficult for the consumers or users to locate the remote control. Accordingly, it would be desirable to provide improved techniques for providing a mobile device based control device locator.

In that embodiment, the instruction information may be representative of at least one operating system 288, one or more applications, which may include, but is not limited to, remote application 290.

In an embodiment, the operating system 288 may include, without limitation, mobile operating systems (e.g., Apple®, iOS®, Google® Android®, HP® WebOS®, Microsoft® Windows Phone®, Microsoft® Windows®, etc.) general arranged to manage hardware resources (e.g., one or more components of the mobile device 118-1) and/or software resources (e.g., one or more applications of the mobile device 118-1).

In an embodiment the remote application 290 may be generally arranged to provide user input information to the media device 114-1 based on received touch input information and assisting a user of the control device 116-1 in determining the approximate physical location of the control device 116-1.

In an embodiment, the remote application 290 may be configured to request to establish a direct connection 202 with the control device 116-1, in response to receiving touch input information from the touch sensitive display component 282 indicating a request by the user to initiate the location of the control device 116-1. For example, the remote application 290 may be configured to request to establish a direct wireless connection utilizing one or more Bluetooth standards, Wi-Fi standards (e.g., Wi-Fi Direct, Wi-Fi Peer-to Peer (P2P), etc.), and/or NFC standards, where no intermediary devices (e.g., media device 114-1, platform server device 120, network devices (access points, routers, etc.), network 150, etc.) are present in the connection between the mobile device 118-1 and the control device 116-1.

Alternatively, the remote application 290 may also be configured to request to establish an indirect connection 204 with the control device 116-1, in response to receiving touch input information to initiate the location of the control device 116-1. For example, the remote application 290 may be configured to establish an indirect wireless connection utilizing one or more wireless communication standards (e.g., cellular standards, Wi-Fi standards, etc.), where at least one intermediary device (e.g., media device 114-1, platform server device 120, network devices (access points, routers, etc.), network 150, etc.) is present in the connection between mobile device 118-1 and control device 116-1.

After establishing a direct or indirect connection with control device 116-1, the remote application 290 may be configured to operate in at least a first mode and/or a second mode. During the first mode, the remote application 290 may be configured to request the acoustic information component 290-1, distance component 290-2, and/or the direction component 290-3 to begin determining network and computation delay information, acoustic delay information, distance information, and/or control device direction information, in response to receiving touch input information to initiate the location of the control device 116-1.

In an embodiment and during the first mode, the acoustic token component 290-6 may be configured to generate and/or provide acoustic token transmission information in response to a request for acoustic token transmission information. The acoustic token transmission information may include, without limitation, waveform information (e.g., square wave, sinusoidal wave, saw tooth wave, etc.), frequency information (e.g., 10 kHz, 15 kHz, etc.), phase shift information (e.g., 0 degrees, 45 degrees, 90 degrees, etc.), power information (e.g., 500 mW, 1 W, 5 W, 10 W, etc.), duration information (e.g., 250 ms, 500 ms, 1 second, etc.), or any combination thereof.

In an embodiment and during the first mode, the acoustic information component 290-1 may be configured to determine various approximate delays between the control device 116-1 and the mobile device 118-1, in response to a request from the remote application 290 to determine network and computation delay information and acoustic delay information. To determine the various approximate delays between the mobile device 118-1 and the control device 116-1, in an embodiment, the acoustic information component 290-1 may be configured to determine network and computation delay information and acoustic delay information for at least one acoustic sensor of the acoustic I/O component 262.

To determine the network and computation delay information and acoustic delay information during the first mode, in an embodiment, the acoustic information component 290-1 may be configured to request an acoustic token component 290-6 to generate acoustic token transmission information. The acoustic information component 290-1 may be further configured to transmit the generated acoustic token transmission information to the control device 116-1 via the established indirect or direct wireless connection, receive acknowledgement information from the control device 116-1 via the established indirect or direct wireless connection.

By way of example, the acoustic token component 290-6 may generate and/or provide acoustic token transmission information to the acoustic information component 290-1, which may include, without limitation, waveform information (e.g., sinusoidal wave), frequency information (e.g., 10 kHz), phase shift information (e.g., 0 degrees), power information (e.g., 2 W), and/or duration information (e.g., 1 second). The acoustic information component 290-1 may then transmit, via the established direct or indirect network connection, the generated acoustic token transmission information to the acoustic information component 240-1 of the control device 116-1 in order for the control device 116-1 to generate, for example, a 10 kHz sinusoidal acoustic tone with 0 degree phase, at 2 watts for 1 second. In response, the acoustic information component 290-1 may receive control device acknowledgement information from the control device 116-1 via the same established direct or indirect network connection.

Substantially simultaneous or contemporaneous (e.g., within 100 microseconds, 10 microseconds, 1 microsecond, etc.) to the transmission of the acoustic token transmission information during the first mode, the acoustic information component 290-1 may also be configured to reset and initiate a high resolution timer (e.g., within 1 microsecond resolution, 100 nanoseconds resolution, etc.). Upon receiving the control device acknowledgement information from the control device 116-1 via the direct or indirect wireless connection during the first mode, the acoustic information component 290-1 may store a value of the high resolution timer in memory 252. The stored value may be the round trip network and computation delay, where half of the stored value may be an estimate of one way network and computation delay and may be represented as the network and computation delay information. It may be appreciated that the network and computation delay information may be indicative of the aggregate time required for the control device 116-1 to: (1) receive the acoustic token transmission information, (2) process the acoustic token transmission information, (3) generate an acoustic token signal based on the acoustic token transmission information, and (4) start or begin the emission of the acoustic token signal by the control device 116-1 via the acoustic I/O component 216.

Substantially simultaneous or contemporaneous to the transmission of the generated acoustic token transmission information (e.g., within 100 nanoseconds, etc.) or a short period of time before the transmission of the generated acoustic token transmission information (e.g., 500 milliseconds before, etc.) during the first mode, the acoustic information component 290-1 may also be configured to continuously receive acoustic signals from the environment as acoustic input information for one or more acoustic sensors 262-1-c of the acoustic I/O component 262, where the acoustic signals may include, among other acoustic signals, the acoustic token signal generated and emitted by the control device 116-1. It may be appreciated the acoustic information component 290-1 may buffer or store at least a portion of the acoustic signal (e.g., 250 milliseconds, 500 milliseconds, etc.) and corresponding values of the high resolution timer as acoustic sensor information in memory 252 for one or more acoustic sensors 262-1-c utilizing the acoustic I/O component 262.

Upon buffering or storing the acoustic sensor information including the acoustic token signal generated in accordance with the acoustic token transmission information for one or more acoustic sensors 262-1-c during the first mode, the acoustic information component 290-1 may detect and determine the time of when the acoustic token signal was first received by, for example, correlating and comparing the acoustic sensor information with the generated acoustic token transmission information, and determining the time based on the corresponding values of the high resolution timer. For each of the one or more acoustic sensors 262-1-c, a value associated with the high resolution timer may be stored based on the detection and determination of the time of when the acoustic token signal was first received by the mobile device 118-1. It may be appreciated that due to physical arrangement of one or more acoustic sensors 262-1-c in the mobile device 118-1 and the actual location of the control device 116-1 emitting the acoustic token signal, some of the acoustic sensors of the one or more acoustic sensors 262-1-c may receive the acoustic token signal at a different time than others acoustic sensors. Thus, each value may be indicative of the time when the acoustic token signal was first received by a particular acoustic sensor of one or more acoustic sensors 262-1-c, which may be represented as aggregate acoustic delay information.

In an embodiment and during the first mode, the acoustic information component 290-1 may be further configured to determine the acoustic delay information for each of the one or more acoustic sensors 262-1-c, based on the difference between the aggregate acoustic delay information for each of the one or more acoustic sensors 262-1-c and the network and computation delay information. In an embodiment and during the first mode, the acoustic information component 290-1 may be configured to determine sound speed information representative of the speed of sound based on one or more environmental factors. The one or more environmental factors may include a temperature, a pressure (e.g., altitude, etc.), humidity, or any combination thereof near the proximity of the mobile device 118-1. It may be appreciated the environmental factors may be determined by the mobile device 118-1 by interfacing with readily available online weather datastores based on location information provided by the location component 276 of the mobile device 118-1.

In an embodiment and during the first mode, based on the acoustic delay information for at least one acoustic sensor of the one or more acoustic sensors 262-1-c, and the sound speed information, the distance component 290-2 may be configured to calculate an approximate distance between the mobile device 118-1 and the control device 116-1, which may be represented by distance information. Additionally or alternatively, based on an average of the acoustic delay information for a plurality of acoustic sensors 262-1-c, and the sound speed information, the distance component 290-2 may be configured to calculate an approximate distance between the mobile device 118-1 and the control device 116-1, which may also be represented by the distance information.

In addition to or alternative to the determination of distance between the mobile device 118-1 and the control device 116-1, in an embodiment and during the first mode, the direction component 290-3 may be configured to determine direction information by comparing acoustic delay information between at least two acoustic sensors 262-1-c to determine paired acoustic delay information. Additionally or alternatively, the direction component 290-3 may be configured to utilize time delay estimation techniques to determine paired acoustic delay information.

By way of example, the direction component 290-3 may be configured to compare the stored acoustic signal information for pairs of acoustic sensors 262-1-c to determine paired acoustic delay information utilizing one or more time delay estimation algorithms, which may include, without limitation, cross correlation algorithm, generalized cross correlation algorithm (GCC), phase transform algorithm (PHAT), and the like. It may be appreciated that the one or more time delay estimation algorithms may be further configured to determine paired acoustic delay information utilizing substantially the acoustic token signal for acoustic signal information of each acoustic sensor.

In an embodiment and during the first mode, the direction component 290-3 may be further configured with acoustic sensor arrangement information representative of one or more algorithms for determining control device direction information and physical distances and angles between the acoustic sensors 262-1-c. For example, the direction component 290-3 may be configured to determine the control device direction information based on the acoustic sensor arrangement information, the sound speed information, and one or more paired time delay information.

It may be appreciated that at least one technical advantage that may be realized in using a specific acoustic token signal generated in accordance with acoustic token transmission information, is that the determination of distance information and control device direction information is possible even in noisy environments. Additionally, by having the control device 116-1 emit a distinct acoustic token signal, a user may also easily identify and locate the control device 116-1 based on hearing in conjunction with the information displayed in the control device location UI view 450 on a mobile device 118-1.

As previously discussed above, in addition to the first mode, the remote application 290 may also operate in the second mode, which may be in addition to or alternative to the first mode. During the second mode, the remote application 290 may be configured to request the control device 116-1 to determine network and computation delay information, acoustic delay information, distance information, and/or mobile device direction information, in response to receiving touch input information to initiate the location of the control device 116-1.

In an embodiment and during the second mode, the acoustic token component 290-6 may be configured to receive acoustic token transmission information from the control device 116-1. In response to receiving acoustic token transmission information from the control device 116-1, the acoustic token component 290-6 may provide acoustic output information to the acoustic I/O component 262 in order to generate an acoustic token signal in accordance with the received acoustic token transmission information. Thus, the acoustic output information may be generated by the acoustic token component 290-6 based on the received acoustic token transmission information. Substantially simultaneous or contemporaneous (e.g., within 100 microseconds, 10 microseconds, etc.) to the providing of the acoustic output information to the acoustic I/O component 262 during the second mode, the acoustic token component 290-6 may also be configured to provide mobile device acknowledgement information via the established direct and/or indirect wireless connection to the control device 116-1.

In an embodiment and during the second mode, the remote application 290 may be configured to receive the network and computation delay information, acoustic delay information, distance information, and/or control device direction information from the control device 116-1, which may be subsequently utilized by the visual component 290-4 for visual presentation and/or feedback component 290-5 for providing haptic and/or auditory feedback. Additionally or alternatively, the remote application 290 may also be configured to translate the received mobile device direction information, generated from the perspective of the control device 116-1 to control device direction information by, for example, shifting the received mobile device direction information by 180 degrees.

In an embodiment, the visual component 290-4 may be configured to visually present one or more UI views including one or more UI elements to enable a user to initiate in the determination of the physical location of a lost control device 116-1. For example, the visual component 290-4 may be configured to visually present control device location initiation UI view 400 of FIG. 4A on the display device of the touch sensitive display component 282 and receive touch input information from the touch sensitive display component 282 to initiate the location of the control device 116-1.

Additionally or alternatively, the visual component 290-4 may also be configured to visually present and update, in substantially real-time control device location UI view 450. For example, the visual component 290-4 may be configured to visually present, in substantially real-time, one or more UI elements of the control device location UI view 450 based on location information received from location component 276, the motion information received from acceleration component 280, orientation information from the orientation component 264, distance information generated by the distance component 290-2 or distance component 240-2, and/or control device direction information generated by the direction component 290-3 or translated from mobile device direction information generated by direction component 240-3.

In an embodiment, the feedback component 290-5, may be configured to provide auditory and/or haptic feedback to the user. In an embodiment, the feedback component 290-5 may be configured to generate feedback information based on the distance information and/or direction information. The feedback information may include, without limitation, pulse waveform information (e.g., square wave, sinusoidal wave, saw tooth wave, etc.), pulse frequency information (e.g., 5 kHz, 10 kHz, 15 kHz for each pulse, etc.), pulse power information (e.g., 500 mW, 1 W, 5 W, 10 W, etc.), pulse duration information (e.g., 250 ms, 500 ms, 1 second duration for each pulse etc.), and/or pulse gap information (e.g., 500 ms, 1 second, 2 seconds gap between each pulse, etc.).

In an embodiment, the feedback component 290-5 may generate pulse frequency information of the feedback information as a function of control device direction information, where the generated pulse frequency information may be higher (e.g., 8 kHz), when the direction information indicates that the approximate location of the acoustic token signal and accordingly the control device 116-1 may be directly in front of the mobile device 118-1. Similarly, the frequency may be lower (e.g., 2 kHz), when the control device direction information indicates that the approximate location of the acoustic token signal and accordingly the control device 116-1 may be directly behind of the mobile device 118-1.

Additionally or alternatively, the feedback component 290-5 may generate the pulse gap information and/or the pulse duration information as a function of distance information, where the generated pulse gap information may be longer (e.g., every 2 second) and pulse duration information may be shorter (e.g., 500 ms), when the distance information indicates that the approximate location of the acoustic token signal and accordingly the control device 116-1 is further away from the mobile device 118-1. Similarly, the pulse gap information may be shorter (e.g., every 250 ms) and pulse duration information may be longer (e.g., 1 second), when the distance information indicates that the location of the acoustic token signal and accordingly the control device 116-1 may be very close to the mobile device 118-1.

In an embodiment, the feedback component 290-5 may be configured to convert the generated feedback information to acoustic output information and/or haptic output information, and provide the acoustic output information and/or the haptic output information to the acoustic I/O component 262 and/or haptic component 272, respectively, in order to emit sound and/or mechanical vibrations in accordance with the generated feedback information.

In a non-limiting example, when the mobile device 118-1 determines that a control device 116-1 is directly in front and is also very close to the mobile device 118-1, the mobile device 118-1 may emit sound with a sinusoidal wave having a frequency of the 8 kHz for duration of 1 second, and repeating after 250 ms have elapsed. Additionally or alternatively, mobile device 118-1 may also emit mechanical vibrations with a sinusoidal wave having a frequency of the 8 kHz for duration of 1 second, and repeating after 250 ms have elapsed.

In another non-limiting example, when the mobile device 118-1 determines that the control device 116-1 is behind and distant to the mobile device 118-1, the mobile device 118-1 may emit sound with a sinusoidal wave having a frequency of the 2 kHz for duration of 500 ms, and repeating after 2 seconds have elapsed. Additionally or alternatively, mobile device 118-1 may also emit mechanical vibrations with a sinusoidal wave having a frequency of 2 kHz for duration of 500 ms, and repeating after 2 seconds have elapsed.

The communications component 210 may include, among other elements, radio frequency circuit(s) configured for encoding and/or decoding information and receiving and/or transmitting the encoded information as radio signals in frequencies consistent with the one or more wireless communications standards (e.g., Wireless IEEE 802.11, Bluetooth standards, Near Field Communications (NFC) standards, etc.). Additionally, the communications component 210 may further include, among other elements, infrared emitter circuit(s) to communicate directly and/or indirectly with previously discussed devices and systems.

In an embodiment, the acoustic I/O component 216 may be generally arranged for converting sound, vibrations, or any other mechanical waves received into digital or electronic signals representative of acoustic input information utilizing one or more acoustic sensors 216-1-e (e.g., microphones, etc.), which may be located or positioned on or within the housing, case, or enclosure of the control device 116-1 to form an microphone array. The I/O component 216 may be configured to provide acoustic input information for each of the one or more acoustic sensors 216-1-e. Additionally, the acoustic I/O component 216 may be further arranged to receive acoustic output information and convert the received acoustic output information into electronic signals to output sound, vibrations, or any other mechanical waves utilizing the one or more electroacoustic transducers 216-2-f (e.g., speakers, etc.).

In an embodiment, the input component 218 may be generally arranged to receive user input(s) via a keypad (not shown) and provide the user input information representative of user inputs to the media device 114-1. For example, the input component 218 may receive user input(s) such as key presses on the keypad, generate user input information based on the key presses, and transmit user input information to the media device 114-1 via communications component 210.

In an embodiment, the memory 212 may include instruction information arranged for execution by the processor component 214. In that embodiment, the instruction information may optionally include, among other instruction information, an embedded operating system 242, and one or more applications, which may include, but is not limited to, control application 240. The optional embedded operating system 242 may include operating systems general arranged to manage hardware resources (e.g., one or more components of the control device 116-1) and/or software resources (e.g., one or more applications of the control device 116-1).

In an embodiment, the control application 240 may be generally arranged to provide input information to the media device 114-1 based on received user input information. The control application 240 may include, without limitation, acoustic information component 240-1, distance component 240-2, direction component 240-2, and/or acoustic token component 240-3. In an embodiment, the control application 240 may be configured to establish a direct or indirect connection with the mobile device 118-1, the control application 240 may be configured to receive a request from the mobile device 118-1 to establish a direct or indirect connection as previously discussed with respect to the mobile device 118-1.

After establishing a direct or indirect connection with the mobile device 118-1, the control application 240 may be configured to operate in at least a first mode corresponding to the first mode of the remote application 290 and/or a second mode corresponding to the second mode of the remote application 290.

During the first mode, the control application 240 and in particular, the acoustic token component 240-4 may be configured to receive acoustic token transmission information from the mobile device 118-1. In response to receiving the acoustic token transmission information from the mobile device 118-1, the acoustic token component 240-3 may provide acoustic output information to the acoustic I/O component 216 in order to generate an acoustic signal in accordance with the received acoustic token transmission information, where the acoustic output information may be generated by the acoustic token component 240-4 based on the received acoustic token transmission information. Substantially simultaneous or contemporaneous (e.g., within 100 microseconds, 10 microseconds, 1 microsecond, etc.) to the providing of acoustic output information to the acoustic I/O component 216, the acoustic token component 240-4 may also be configured to provide control device acknowledgement information via the established direct and/or indirect wireless connection to the mobile device 118-1.

During the second mode, the control application 240 may be configured to receive a request from the mobile device 118-1 to begin the determination of network and computation delay information, acoustic delay information, distance information, and/or mobile device direction information. In an embodiment and during the second mode, the control application 240 may request the acoustic information component 240-1 to determine network and computation delay information and acoustic delay information.

In an embodiment and during the second mode, the acoustic information component 240-1 may be configured to determine various approximate delays between the control device 116-1 and the mobile device 118-1, in response to a request from the control application 240 to determine network and computation delay information and acoustic delay information.

To determine the various approximate delays between mobile device 118-1 and the control device 116-1 during the second mode, in an embodiment, the acoustic information component 290-1 may be configured to determine network and computation delay information and acoustic delay information for at least one acoustic sensor of the acoustic input/output (I/O) component 216.

To determine the network and computation delay information and acoustic delay information during the second mode, in an embodiment, the acoustic information component 240-1 may be configured to request an acoustic token component 240-4 to generate acoustic token transmission information. The acoustic information component 240-1 may be further configured to transmit the generated acoustic token transmission information to the mobile device 118-1 via the established indirect or direct wireless connection, receive mobile device acknowledgement information from the mobile device 118-1 via the established indirect or direct wireless connection.

In an embodiment and during the second mode, the acoustic token component 240-4 may be configured to generate and/or provide acoustic token transmission information in response to a request for acoustic token transmission information. The acoustic token transmission information may contain information similar to those previously discussed with respect to mobile device 118-1.

Substantially simultaneous or contemporaneous (e.g., within 100 microseconds, 10 microseconds, 1 microsecond, etc.) to the transmission of the acoustic token transmission information to the mobile device 118-1 during the second mode, the acoustic information component 240-1 may also be configured to reset and initiate a high resolution timer (e.g., within 1 microsecond resolution, 100 nanoseconds resolution, etc.). Upon receiving the mobile device acknowledgement information from the mobile device 118-1 via the direct or indirect wireless connection during the second mode, the acoustic information component 240-1 may store a value of the high resolution timer in memory 252. The stored value may be representative of the round trip network and computation delay, where half of the stored value may be an estimate of one way network and computation delay and may be represented as the network and computation delay information. It may be appreciated that the network and computation delay information may be indicative of the aggregate time required for the mobile device 118-1 to: (1) receive the acoustic token transmission information, (2) process the acoustic token transmission information, (3) generate an acoustic token signal based on the acoustic token transmission information, and (4) start the transmission of the acoustic token signal by the mobile device 118-1 via the acoustic I/O component 262.

Substantially simultaneous or contemporaneous to the transmission of the generated acoustic token transmission information (e.g., within 100 nanoseconds, etc.) or a short period of time before the transmission of the generated acoustic token transmission information (e.g., 500 millisecond before, etc.), the acoustic information component 240-1 may also be configured to continuously receive and store acoustic signals from the environment as acoustic input information for one or more acoustic sensors 216-1-e of the acoustic I/O component 216, where the acoustic signals may include, among other acoustic signals, the acoustic token signal generated and emitted by mobile device 118-1. It may be appreciated the acoustic information component 240-1 may receive and buffer or store at least a portion of the acoustic signals (e.g., 250 milliseconds, 500 milliseconds, etc.) and corresponding values of the high resolution timer as acoustic sensor information in memory 212 for one or more acoustic sensors 216-1-e utilizing the acoustic I/O component 216.

Upon buffering or storing the acoustic sensor information including the acoustic token signal generated in accordance with the acoustic token transmission information for one or more acoustic sensors 216-1-e during the second mode, the acoustic information component 290-1 may detect and determine the time of when the acoustic token signal was first received by, for example, correlating and comparing the acoustic sensor information with the generated acoustic token transmission information, and determining the time based on the corresponding values of the high resolution timer. For each of the one or more acoustic sensors 216-1-e, a value associated with the high resolution timer may be stored based on the detection and determination of the time of when the acoustic token signal was first received by the control device 116-1. It may be appreciated that due to physical arrangement of one or more acoustic sensors 216-1-e in the control device 116-1 and the actual location of the mobile device 118-1 emitting the acoustic token signal, some of the acoustic sensors of the one or more acoustic sensors 216-1-e may receive the acoustic token signal at a different time than others acoustic sensors. Thus, each value may be indicative of the time when the acoustic token signal was first received by a particular acoustic sensor of one or more acoustic sensors 216-1-e, which may be represented as aggregate acoustic delay information.

In an embodiment and during the second mode, the acoustic information component 240-1 may be further configured to determine the acoustic delay information for each of the one or more acoustic sensors 216-1-e, based on the difference between the aggregate acoustic delay information for each of the one or more acoustic sensors 216-1-e and the network and computation delay information. In an embodiment, the acoustic information component 240-1 may be configured to determine sound speed information representative of the speed of sound based on one or more environmental factors. The one or more environmental factors may include a temperature, a pressure (e.g., altitude, etc.), humidity or any combination thereof near the proximity of the control device 116-1. It may be appreciated the environmental factors may be determined by the control device 116-1 by interfacing with readily available online weather datastores based on geographic information previously discussed for the user of the media device 114-1. Additionally or alternatively, the one or more environmental factors may also be preprogrammed.

In an embodiment and during the second mode, based on the acoustic delay information for at least one acoustic sensor of the one or more acoustic sensors 216-1-e, and the sound speed information, the distance component 240-2 may be configured to calculate an approximate distance between the mobile device 118-1 and the control device 116-1, which may be represented as distance information. Additionally or alternatively, the distance component 240-2 may be configured to calculate an approximate distance between the mobile device 118-1 and the control device 116-1 based on an average of the acoustic delay information for a plurality of acoustic sensors 216-1-e and the sound speed information.

In addition to or alternative to the determination of distance between the mobile device 118-1 and the control device 116-1 by the control device 116-1 during the second mode, in an embodiment, the direction component 240-3 may be configured to determine direction information by comparing acoustic delay information between at least two acoustic sensors 216-1-e to determine paired acoustic delay information. Additionally or alternatively, the direction component 240-3 may be configured to utilize time delay estimation techniques for determining paired acoustic delay information as previously discussed with respect to direction component 290-3.

In an embodiment and during the second mode, the direction component 240-3 may be further configured with acoustic sensor arrangement information representative of one or more algorithms for determining direction information and physical distances and angles between the acoustic sensors 216-1-e, and determine the mobile device direction information based on the acoustic sensor arrangement information, the sound speed information, and one or more paired acoustic delay information.

After the direction component 240-3 determines the mobile device direction information during the second mode, the control application 240 may be configured to transmit acoustic delay information, distance information, and/or mobile device direction information to the mobile device 118-1 for further processing, visual presentation, and/or acoustic and/or haptic feedback.

In an embodiment, the mobile device direction UI element 468 may be visually presented and continuously updated in substantially real-time to indicate the current heading of the mobile device 118-1. It may be appreciated that the visually presented current heading, which may be an arrow pointing to the current heading of the mobile device 118-1, may vary by size, color, shape, and/or the like. This heading may be synchronized or locked to the orientation of the mobile device 118-1. Alternatively, the heading may be determined based on orientation information received from the orientation component 264.

In an embodiment, the graphical distance and direction UI element 474 may be visually presented and continuously updated in substantially real-time to indicate the current distance and direction of the control device 116-1 with respect to the current heading of the mobile device 118-1 based on the control device direction information, distance information, and/or orientation information. It may be appreciated that the visually presented current distance and direction of the control device 116-1, which may be an arrow pointing to an approximate location of the control device 116-1, may vary by size, color, shape, and/or the like.

By way of example, the length of the arrow of the distance and direction UI element 474 may be a function of the distance information, so that the farther the control device 116-1 is from the mobile device 118-1, the longer the arrow up to a maximum length. Similarly, the closer the control device 116-1 is from the mobile device 118-1, the shorter the arrow up to a minimum length.

Provided herein are some of the processing operations that may be performed by one or more example embodiments. Although some of the processing operations may appear to be performed sequentially, it may be appreciated that the processing operations may not be limited to the order as illustrated and/or described. Additionally, some of the processing operations may even occur substantially simultaneously or contemporaneously with respect to other processing operations.

FIG. 5A illustrates processing operations that may be performed by the processor component 254 of a mobile device and processor component 214 of a control device with respect to the first mode.

With respect to a mobile device, at step 510, mobile device may receive request to locate control device. For example, mobile device 118-1 may receive request from user to locate control device 116-1. At step 512, mobile device may establish connection with control device 512. For example, mobile device 118-1 may request to establish a direct or indirect wireless connection with the control device 116-1. At step 514, the mobile device may generate acoustic token transmission information. For example, mobile device 118-1 may generate acoustic token transmission information, which may include, without limitation, waveform information, frequency information, phase shift information, power information, and/or duration information. At step 516, mobile device may transmit acoustic token information and initiate timer. For example, mobile device 118-1 may transmit acoustic token information to the control device 116-1 and substantially contemporaneous or simultaneous to the transmission, the mobile device 118-1 may also initialize or reset a high resolution timer.

At step 518, the mobile device may store acoustic sensor information. For example, mobile device 118-1 may store or buffer at least a portion of acoustic input information received from control device 116-1 via acoustic I/O component 262 and associated values of the high resolution timer as acoustic sensor information for each of the one or more acoustic sensors 262-1-c. At step 520, the mobile device may determine aggregate acoustic delay information. For example, mobile device 118-1 may determine the aggregate acoustic delay information by correlating and comparing the acoustic sensor information with the generated acoustic token transmission information. At step 522, the mobile device may receive control device acknowledgement information and store timer. For example, the mobile device 118-1 may receive control device acknowledgement information transmitted from control device 116-1 and substantially contemporaneous or simultaneous to the receipt, the mobile device 118-1 may store the value of the high resolution timer.

At step 524, mobile device may determine acoustic delay information. For example, the mobile device 118-1 may determine acoustic delay information for each of the one or more acoustic sensors 262-1-c based on the stored value of the high resolution timer and aggregate acoustic delay information for each of the one or more acoustic sensors 262-1-c. At step 526, mobile device may determine distance information. For example, the mobile device 118-1 may determine distance information based at least partially on acoustic delay information for at least one acoustic sensor of the one or more acoustic sensors 262-1-c and/or sound speed information.

At step 526, mobile device may determine direction information. For example, the mobile device 118-1 may determine control device direction information based at least partially on the acoustic sensor arrangement information, the sound speed information, and/or one or more paired time delay information.
